Week One: FridayJust arrived in Vegas...staying in a four-bedroom (high-rolling) villa with a waterfall in the foyer—and full complimentary bar. I've had a long day that started in Telluride interviewing Tom Cruise. Tom's chef prepared ribs and chicken for lunch. I had salad and corn on the cob with no butter and a kale salad, which was also offered. There were also home made chocolate brownies with marshmallow filling made by Tom's mom, which I also turned down. I feel like I let Tom's mom down, but I explained that I had agreed to do this cleanse for 21 days—and was only on my sixth day.

Then I walk into this suite that's so fancy there's an electronic device to flush the toilet, and the first thing I notice is the bar with the cosmo glasses.

My assistant who's on the cleanse with me says, "Boy, wouldn't a cosmo be great right now?" "Yes, it would," I say...and I made us an alcohol-free one.

So we sit here with our alcohol-free sparkling water with a dash of cranberry and fresh-squeezed lime thinking about our consciousness.

On our way now to see Tina and Cher rehearse. Any other time I would be hangin' with Tina afterward, drinking champagne. Going to come back and get a massage instead.

Kathy Freston's Comments: Remember, if you slip, it's okay. You are leaning into a clean and conscious diet; no need to force yourself into something that is terribly uncomfortable. Do the best you can, taking baby steps until you feel comfortable and ready to embrace it wholeheartedly.
